OTTO KAUFMANN, OF BERLIN, GERMANY.

PICTURE-CARD.

SPECIFICATION forming part of Letters Patent No. 418,185, dated December24, 1889. Application filed August 3l, 1889. Serial No. 322,604. (Nomodel.) Patented in Germany .Iuly 24,1889, No. 48,717.

T0 all whom it may concern,.-

Be it known that I, OTTO KAUEMANN, a subject of the King of Prussia andEmperor of Germany, and a resident of the city of Berlin, in the GermanEmpire, have invented certain new and useful Improvements in Picture-Cards, (for which Letters Patent were obtained in Germany under date ofJuly 24, 1889, No. 48,712) of which the following is a specification.

This invention relates to an improved picture-card which is soconstructed that the picture on the surface of the card may be changedinto a pic-ture differingin colors and contours, so as to produce averyeli'ective and pleasing effect; and the invention consists of apicture-card which is formed of two congruent pictures, of which one ison the rear wall of the card and the other on a transparent fabric infront of the same, said pictures being separated by an intermediateslidepiece which is guided in a frame attached to the rear part of thecard.

`In the accompanying drawings, Figures 1 and 2 represent frontelevations of my improved picture-card, showing the same respectivelybefore and after withdrawing the intermediate supporting slide-piece.Eig. 3 is a vertical transverse section on line 1l, Fig. l.

Similar letters of reference indicate corresponding parts.

A represents a case or frame of suitable card-board, which is made in amanner corresponding to the leaves of photographalbums. l

On the inner surface of the rear wall of the case or frame A is printeda picture in suitable colors, which picture matches in its con tours,either partly or entirely, a similar picture l), which is printed on asheet of transparent material B, such as line silk gauze, of that kindused as bolting-cloth- This sheet of transparent material is pasted tothe under side of the front or mat of the case A, and is separated `fromthe lower picture by means of a non-transparent piece or plate ofcard-board C, which is guided in ways between the frame and preventedfrom being pulled out entirely by means of a stop-shoulder d at theinner edge, which abut-svagainst a shoulder d at the open end of thecase A. The tints in which the picture on the transparent sheet isprinted are preferably pro` duced in soft neutral colors, while thecolors of the picture on the rear wall of the case A are printed inbright colors, so that when the intermediate slide-plate is drawn outthe lower picture blends with the upper picture and imparts a bright andpleasant effect to the same, as the bright colors of the lower pictureappear through the fine transparent gauze on which the upper picture isprinted and are softened by the neutral tintsI of the upper picture.

A great many different combinations of pictures may be made. Forinstance, a child printed on the transparent sheet may be transformedinto an angel if the congruent picture of the child on the lower sheetis provided with wings, while the figure on the upper picture has nowings. In a similar manner a restful forest landscape may be so changedthat the same assumes on removing the slideplate the character of ahunting scene, or the dawn of morning may be changed into brightsunrise, dto., in which case the lower picture has the complementaryfigures and additions which are not shown on the upper picture. Thebright or subdued character of the upper picture is brought out inrelief by a proper tint or color of the int-ermediate slide-plate.

Having thus described myinvention, I claim as new and desire to secureby Letters Patent- A picture-card composed of a case or frame providedwith a picture on the rear wall of said case, a transparent sheet havinga picture congruent with the contours of the lower picture, and anintermediate slide-plate that may be drawn out so as to produce thematching and blending' of the pictures, substantially as set forth.

In testimony that I claim the foregoing as my invention I havesigned myname in presence of two subscribing Witnessesl OTTO KAUFMANN. Witnesses:
